MANUFACTURE OF SHEET-METAL FENDERS.

SPECIFICATION forming part of Letters Patent No. 538,883, dated May '7, 18935.

Application filed October 3, 1893.

Serial No. 487,097- (No model.)

To aZZ whom it may concern/.-

Be it known that I, GEORGE RUSSELL, a resident of McKeesport, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in the Manufacture of Sheet-Metal Fenders; and I do hereby declare the following to-be a'full, clear, and exact description thereof.

My invention relates to the manufacture of sheet metal fenders, its object being to provide a fender which is light in weight and firmly braced to withstand the severe wear and tear to which it is exposed.

My invention consists in certain improvements all of which will be fully hereinafter set forth and claimed.

To enable others skilled in the art to make and use my invention, I will describe the same more fully, referringv to the accompanying drawings, inwhich v Figure 1 is a top View of my improved fender. Fig. 2 is a rear view. Fig. 3 is a perspective view of the removable top ridge. Fig. 4 is a sectional View on the line 4. 4:, Fig. 1. Fig. 5 is a view of the fender-blank before it is bent to form the fender, and Figs. 6 and 7 are detail sectional views on an enlarged scale.

Like letters indicate like parts in each view.

The body of the fender which includes the front a, the ends I) and apron c, is formed from the blank shown in Fig. 5 in which the parts corresponding to the front ends and apron are marked with the same reference letters. The front corners of the blank are slit diagonally as at d,or, if desired, a triangular portion indicated by dotted lines in Fig. 5 may be cut from said cornersn The blank so formed is then bent to form the fender body by suitable machinery. It is apparent that by having the front corners of the blank slit in the manner described it is only necessary to bend down the front a and ends I) when the fender body is formed. The apron c is seamless and the only seams in the fender body are at the front corners. These corners are provided with corner pieces e in the finished fender. The top ridge f is formed separate from the body of the fender and is secured thereto by means of the bolts f. This top ridge f is formed from a metal plate so bent as to form a hollow body,

and the ridge thus formed has its ends bent so that it conforms to the outer margin of the fender body to which it is then secured. As I have illustrated my invention in connection with a fender provided with a guard rail g, the bolts f pass down through the hollow posts h and through openings t' in the apron c. Nuts kengage with the threaded ends of the bolts f in the lower face of said apron c and so act to secure the top ridgefrigidly in place.

In case the fender is employed without the guard rail, the top ridgefis formed with the inwardly projecting flanges I which form the slot m. A bolt it passes through said slot, a nut 0 and washer p if required being interposed between the head of said bolt n and the inwardly projecting flanges Z, while a nut q and washer r engage said bolt n after said bolt has passed through an opening in the apron c. Other means for securing the top ridge f to the body of the fender may, however, be employed.

To brace the apron and the ends of the fender a wire rod 3 is employed. This wire rod 8 has the ends thereof bent at right angles to the main portion and said ends are secured to the feet I) of the ends I) of the fender. For this purpose the tongues tare formed on said feet and said tongues when bent back act to retain the ends of the wire rod 3 securely in place. The wire rod 3 extends up at an angle and passes along the front edge of the apron c. The rear edge of said apron is bent over to envelop said wire rod 8 to form a bead ing M. In this manner the rear edge of the apron is prevented from splitting or warping and a firm solid edge is presented, while the inclined portions of said wire rod extending from the feet of the ends b act to support said apron.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination with a fender, of a top ridge removably secured thereto, said top ridge being formed of a metal'strip bent to form a hollow body which body is bent at its ends to conform to the margin of the fender to which it is secured, substantially as set forth.

2. The combination with a fender body, of a top ridge, said top ridge being formed of a metal strip bent to form a hollow body, which body is bent at is ends to conform to the margin of said fender body, a bolt or rivet securing said top ridge to said fender body, substantially as set forth.

3. The combination with a fender body, of a guard rail and supporting posts, a removable top ridge, and bolts extending from said posts through said top ridge and through the fender body to secure same to fender body, substantially as set forth.

4. The combination with a fender body, of a removable top ridge having inwardly projecting flanges and a slot between the same, bolts or rivets passing through said slots to secure said top ridge to said fender body, substantially as set forth.

5. The combination with a fender body having downwardly bent end portions, a heading along the outer edge of the apron, a bent rod connected at its end to the lower edges of said end portions and extending thence upwardly and engaged by said beading, substantially as and for the purposes set forth.

In testimony whereof I, the said GEORGE RUssELL, have hereunto set my hand.

GEORGE RUSSELL.
